8 Claims. (Cl. 106-8) 'The present invention relates to improvements inpolishes and more particularly to improve- -ments in emulsifiedcleansing and polishing compositions for painted, enameled, varnished,lacquered and highly finished surfaces and the like. The composition ofthe present invention is particularly adapted for use in connection withthe finished surfaces of automobile bodies but may be advantageouslyemployed for cleansing andpolishing furniture and the like.

The present invention provides a wax polish composition which possessesboth cleansing and polishing properties and thereby enables theaccomplishment of both results in a single operation. This is highlydesirable since it provides a polish which requires a minimum of timeand effort to apply. The invention further provides a polish having arelatively high percentage of hard wax and a diatomaceous earth abrasivein a free flowing invert emulsion. Further, our improved polish providesa film of 'hardwax which can be rubbed to a high finish.

Our improved emulsified wax polish comprises the following constituentsin approximately the specified proportions by weight:

' Per cent Organic salt 20 to 50 Hard w to Fatty acid 1.25 to 3 Alkalisalt of a weak mineral acid .75 to 2 Morpholine 0 to 1 Water to 60Abrasive 6 to 10 In the above formula the organic solvent may be apetroleum solvent, and preferably a blend of equal parts of a lightpetroleum distillate having an initial boiling point not less than about360 F. and an end point not more than about 500 F. and a petroleumdistillate having an initial boiling point of about 300 F. to about 312F.

and an end point of between about 418 F. and 430 F. Inspections on twotypical distillates having these requirements are given below:

Distillate A Distillate B About 46-49 A. P. I Not less than l40 F 46-49A. P. I.

G a t i I 3 About 102 F.

F ash Distillation:

Initial 10% oil... 20% ofi. 30% ofi End point Distillate A is apetroleum distillate commonly referred to as No. 9 refined oil anddistillate B is a distillate known as oleum spirits.

The hard wax in the above formulais preferably carnauba wax although itis possible to use other hard waxes, such as montan' wax, Japan wax,candelilla wax or ceresinwax. Any of these waxes can be used alone or inadmixture with each other or in admixture with carnauba wax. We prefer,however, to use carnauba wax alone.

The fatty acid we prefer to employ is oleic acid although other-highmolecular weight fatty acids can be used in place of it.

As the alkali salt of a weak mineral acid we prefer to use borax.However, we have obtained satisfactory results using equivalent amountsof, alkali salts of other weak mineral acids such as sodium carbonate,tri-sodium phosphate and sodium silicate. As the abrasive we haveobtained'best results using a diatomite, preferably of about 200 mesh,such as Semilite. Other mild abrasives, such as other types ofdiatomaceous earths, colloidal clays and the likemay be used, alone orwith Semilite.

vDia'tomite is preferred since it removes the sur face oxidized filmwithout scratching or removingv excessive amounts of the basic paint, asis often the case in usual cleaning and polishing operations.

A typical preferred composition for our improved cleanser and polish isthe following:

Another composition which is very effective is the following:

Per cent No. 9 refined oil 18.5 Oleum spirits 18.5 Carnauba wax 7 Oleicacid-" 1.75 Borax 1.75 Water 44. Semilite Q. 8'

The methodof preparing our improved polish consists in adding the boraxor the borax and .morpholine dissolved in the water slowly to a solutionof the wax and fatty acid dissolved in the petroleum solvent while themixture is continuously agitated. The temperature of the two solutionsshould be above the solution tempera-. ture of the wax in the petroleumsolvent. In the case of our preferred composition this temperature isapproximately 150 F. After the solutions have been mixed together andemulsified the emulsion is cooled to about F. or lower nection withcertain specific embodiments thereof it is to be understood that theseare given by way of illustration and not by way of limitation.
